JH21-250 tons pneumatic punching machine structural features:

1. High rigidity

1. High rigidity and high precision structure, welded with steel plates, heat treated to eliminate the pressure inside the bed.

2. The structural parts are evenly loaded and rigidly balanced.

2. Stable high precision

The friction parts such as crankshaft, gears, gear shafts, etc. are hardened and heat treated before grinding, and have extremely high wear resistance and balance, and stable performance.

3. Reliable and safe operation performance

The clutch/brake device is highly sensitive, and together with the imported double solenoid valve and overload protection device, it ensures the accuracy and safety of the operation and stopping of the punch slide.

4. Production automation and labor saving

It can be matched with any automatic feeding mechanism to run automated production, reduce costs and improve efficiency.

5. Balance of center of gravity

1. The transmission center is consistent with the center of the whole machine, ensuring the precision and stability of stamping.

2. This machine uses two slider balancers to ensure that the machine maintains balanced operation.

6. Slider adjustment mechanism

The adjustment precision is up to 0.1mm, making production adjustment safer and faster.

7. Environmental protection

Advanced design concept, low noise, low consumption, energy saving.
